I think you two are saying basically the same thing, only I can't figure out what that "thing" is. Are you saying HIV positives won't necessarily develop AIDS? Are you saying that monogamy won't prevent others from getting AIDS? In layman's terms, please explain exactly what you ARE saying?
There is bonafide immuno-suppression caused by drug abuse such as poppers which were popular in the 70's and 80's gay communities. Also there was a host of tropical third world diseases among the gays in those wild and wooly decades as well. However, shortly after the first cases of immuno-suppression appeared, an erronoeous coorelation was made by a French scientist to the HIV virus. There were all sorts of irregularities in his research, which was not even subject to peer review before it was accepted as true by uncritical and panicking authorities. Billions of government dollars for research and foreign aid have given the HIV theory ad-hoc legitimacy.
AZT, an insidious poison, has killed thousands upon thousands of healthy people, both gay and straight, who were prescribed it merely for testing HIV positive (which, as already mentioned does not even reliably indicate the presence or absence of the virus). In Africa, diseases long known there were arbitrarily reclassified as AIDS without even a positive test for HIV (because it was deemed to impractical to do HIV tests there.)
One important point is that even bonfide immuno-suppression (e.g. drug-abuse related) is reversable, if the behavior is stopped, i.e. "AIDS" has never been an automatic death sentence, that is, if AZT and the other killer drugs prescribed as a "cure" for it or not taken.
